The Geohelis platform is a university-certified platform for improving the readability of the institution’s technical resources

This platform brings together a centre of analytical resources devoted to the analysis of major chemical and trace elements (inorganic anions/cations, dissolved carbon) of environmental samples (mainly water but also certain minerals, biological samples, etc.) and a second devoted to the elementary and/or isotopic analysis (radiogenic isotopes) of rocks and/or minerals to study the origin, the history and age of terrestrial rocks and of the associated minerals

Scientific manager of the platform : Marc Poujol with the support of Rémi Marsac
Technical managers of the platform : Martine Bouhnik Le Coz and Nathan Cogné with the technical support of Dominique Bavay, Maxime Pattier, Lionel DutruchPatrice Petitjean et David Vilbert,
